Getting the Scavenger achievement in Stranded comes down to finishing every repair at Base Camp, not just collecting a pile of supplies. If you've been looking at MW4 Bot Lobbies, keep that separate from this campaign objective: your progress here depends on exploration and crafting. The tenth mission's open map gives you room to roam, but there's a clear target. Complete twelve camp prompts covering four weapons and eight tactical items. Leaving even one unfinished means you're not done.

Pick up the Vulcan before your next camp visit

The easiest upgrade to overlook is the Vulcan Sniper Rifle's silencer. You can't simply arrive at the crafting table with enough materials and expect it to appear. Head to the SAM site area, find a Vulcan, and physically pick it up. That pickup makes the silencer available at Base Camp for ten supplies. It's worth handling this early. Otherwise, you could finish the visible repairs, think you've cleared the table, and still be missing the prompt that matters.

Know what your supplies need to cover

There's no need to save everything for the most expensive equipment first. Smaller repairs count toward completion too, so work through the available prompts and keep track of what remains. The costs below give you a spending guide, though they don't represent all twelve required items. Five supplies can finish a smaller job; the heavier equipment takes a bigger share. Whatever order you choose, the achievement depends on completing the full set rather than buying only the gear you'll use.

Make each supply run count

Major enemy outposts are your best starting point. Each usually holds fifteen to twenty-five supplies, with large orange bags tucked inside buildings. Search the rooms after a fight, then check defeated soldiers for individual drops. Between outposts, investigate question marks and other marked locations. The twenty-six yellow supply crates offer more collection opportunities while you explore for the fifty-eight hidden notes. A thorough sweep can leave you with nearly two hundred supplies after every camp repair is finished.

Check the camp before moving on

If completion doesn't register, revisit the table rather than immediately hunting for more materials. Players browsing Bot Lobbies MW4 for sale should keep this separate campaign checklist in mind when returning to Stranded. Check that the Vulcan silencer appeared and that every repair was completed. Then try the actions below. They give the game another chance to register equipment you've already restored, without sending you across the map for supplies you might not need.
